Lap Pool Blue vs Opal Silk
Both from Behr's palette. Hue-wise, Lap Pool Blue belongs to the blue family and Opal Silk to the blue-green family. They have nearly identical light reflectance values (44 vs 43), so they'll read as similarly Medium in most lighting conditions. Lap Pool Blue runs green and blue while Opal Silk is decidedly green, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Lap Pool Blue vs Opal Silk in Real Spaces
2 real rooms side by side. Lap Pool Blue and Opal Silk are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
